y This invention relates to tlexible com osivtion shingles or covering umts for roofs, aving ref'abl .downwardly-narrowed .lower portionswhic are exposed when theshingles or units are laid u on a roof andhaving lockin parts or mem ers at their lower ends.

ne of the objects of the invention is the improvement of such shingles or covering units with a view of simplifying their conio struction, reducing their cost of manufacture, and producing a smooth roof without bulges.

Another object .is to so construct the shingles that they can be readily ad]usted both vertically and laterally in layingthein, in order to com eiisate for inequalities or misalinement, an improve the appearance of the roof. .y

In the accompanying drawings: I i0 Fig. lis a fragmentary top p an yview of a roof embodying my invention. Fig 2 is a. similar view on an enlarged scale, showing one of the shin les folded back to expose its retaining or loc ng staples.

Similiar characters of reference lindicate corresponding parts throughout their views. 10 indicates the usual roof boards or sheathing, and 11 the *starting strip of roofing material laid along the lower margin of the roof.

The shingles 12, or covering units as they `may be termed, are preferably constructed of composition roong, such as felt saturated with asphalt and faced with crushed slate or other appropriate material.

When using the particular shape of shingle or covering unit shown in the accompanying drawing,` the shingles or units are laid diagonally in the customary overl ing rows or courses2 with the side corners o `the shingles or units in the saine row or course abut- 50 ting or adjacent to each other, as shown.

yIn all cases, however, the lower portion of wardly-tapered or "are ci substantially diamond shape. Where, 'therefore, reference `is made hereinafter to 1,929. Serial No. 413,875.`

These side corners may be more particularly referred to as lower side corners; especially f when the invention is applied to shingles or units of different outline than those shown in the drawings but in all cases the shingles or units woul he arranged in overyling rows or courses. l v

Roof or covering unitsv are commonly employed in various sha s, and therefore it is within the spirit of t is invention to apply the same to a shingle or unit in any of its common forms, especially since this invention relates to the formation and/or construction of the lower and medial portions of thelshingle ,or unit and its manner of ,attachment or application to a roof; and having especiallyreference to the shingles or units in any particular row or course,- to the manner of attachment or application of the shingles or units in the row or course directly beneath'.

each roong or covering unit has aii'arrowed lower portion or portions, preferably a downwardly-tapered or V-shaped portionor portions, and when applied to a roof the exposed portions of all shingles, when using a dowi- -shaped lower portion,

an individual roofing or covering unit,the lower portions of the shingles o'r units may be V-s ape'd and the intervening spaces be of inverted V-'formation; or such lower por- `tions may be otherwise formed, yet assure display of spaced-apart portions: having in allA cases the appearance of individual shingles, which in some cases they are.

When embodying my invention in and applying the same to individual shin les or units, each shingle or unit is provi ed at its lower end, or corner inthe event of the lower portion being V-sha ed, with a tongue 13, preferably integral wit the. shingle-body and out simultaneously therewith. In the preferred construction shown the tongue is formed by cutting a pairof opplosing notches 14 in the edges of the lower s ingle corner. This manner of ycutting brings the tongue within the dimensional lines of the shingleand reduces waste ofmaterial to ainnimum. 100

Each shingle or unit, in the case of an individual shingle, is rovided at contiguous mar inal portions wit side notches 15, these notches being, more particularl stated, at the side corners of the shingle s own in the drawing, the two alined or registering notches of a air of adjacent or juxtaposed shingles or units together forming a recess 16 adapted to receive the tongue 13 of a similar shin le or unitv in the overlying course,.allowing tY e tongue to lie Hush with the face of the underlying shingles or units, and producing a smooth shingle over its entire surface. In other. words, each course of shingles or units has the recesses 16 at the upper ends of the s aces between the narrowed lowered portions of the shingles or units, which recesses receive the tongues 13 at the lower ends of the shingles or units in the overlying eourse.`

Any appropriate means may be employed to fasten or lock the shingle or unit-tongues 13 in the recesses 16. The preferred devices consist of a pair of L-shaped staplesl 17 driven through the bodies of the shingles or units f at opposite sides of the recesses 16. In all cases, these staples havevtheir heads overhanging or extending over the recesses, and the .tongues 13 of the shingles or units of the overlyin row or course are inserted under' the overanginr portions of said staples, as best shown in liigs. 2, 3 and 6. The heads 18 of these. staples face each other, preferably i without meeting, but are of suiiicient extent to overla the margins of the locking tongue and relia ly hold itin place. .These 'staples' thus serve the double purpose of retaining or. locking the tongue of one shin lie or unit and fastening the underlying s ingles or units; in the selected form of shingle shown in the drawing, the opposing sides, or more particularly side corners, of the pair of underj lying shingles being thus fastened.

In applying or locking a shingle and unit, 'its tongue or tongues may either be left unfolded, as shown in Fig. 2, and inserteduiider the heads of the staples in that'position, and the shingle body then folded over the tongue to the final position shown in Fig. 1; orthe tongue may be turned under the shingle or unit body and the shingle or unit then moved upward to hook the tongue under its'companion staple or staples. In either case, the staples are :fully concealed and protected from the weather by thev shingles or units.

As the tongues of overlying shingles or units enter the notches of underlying shingles or units, the tongues canbe easily inserted under theretaining members 18 or 19 without buckling; and being flush with adjoining shingles or units, the tongues do not produce bulges in the roof, leaving it flat, smooth andsightly'. v

The tongues of vthe rooting or covering shingles or -unitsand theirreceiving recesses 16 are long enough to permit the shingles or ,to adjust the shingles or units laterally-more i 'U-shaped. staples 1.9

y the units, and concealed means for units in the same horizontal row or course and yet retain the tongues with the necessar security to withstand the force of -win storms. i v

As shown in 4Figs. 2 and 3, the recesses 16` are somewhat wider than the ton permit a certainamount of side p ay ofthe tngues. This provision enables the roofer or less at or 'near the end of the'roof, or a valley, tobring the side edges or corners of all shingles or units in the same rowfor course against one another and produce a lsightly, uniformly laid roof.

The several advanta es above described are obtained by an excee ingly simple and in# expensive construction of the shingles or units and their lockingldevices andwithout sacricing the strengt and'security of the lock.

The'L-shaped staples are suitable at *they end s of a roof or valleylas well as at otherl laces, and they are t erefore preferred;

ut any other appropriate means may be substituted for them. For example, ordinary wide enough to bridge the locking tongue and penetrate acent underlying shingles or units may be used, if desired, as shown in Fig. 6.

The term preferably,v wherever herein used, isintended to indicate that other forms,

shapes, or devices may be employed whenever said te-rm has reference to a. form, shape, or device, and that it is to be understood that this term is not to be construed in a vlimited sense. v

Having thus described my invention, what I claim is 1 1. In a roof construction, a pair ofcover-- ing units notched at their opposite side edges,

'forming a recess, a third covering unit overlying said pair of units and provided at its lower end with a lockingtongue lying flush in said recess, the latter bein wider than said tongue, permitting lateral a justment of said third unit relative to saidpair of units, and

means for retaining the tongue in said recess.

2. .In a rooingconstruction; covering units arranged in overlying rows, each row of covering units having downwardly-narrowed lower portions forming upwardly-narrowed i spaces therebetween and having also downwardly-opening recesses at the upper ends of said spaces opening to the latter, said units having locking tongues at the lower ends of their downwardly-narrowed lower portions lying flush in the recesses of the underlying row of units,lsaid recesses being wider than said tongues to permit lateral'a'djustment of fastening said units in place and for retaining saidtong'ues in said recesses. Y. Y. s

3. In a roofing construction, covering units arranged in horizontal rows, one row overlying another, each row of covering units having downwardly-narrowed lower portions Eorming upwardly-narrowed spaces 5 therebetween and having also downwardlyopening recesses at the upper ends of said spaces opening to the latter, said unitshaving locking tongues on their downwardlynarrowed ower portions lying Hush in the recesses of the underlying row of units, said recesses being wider than4 said tongues to permit lateral adjustment of the units andl being also of sufficient length to permit vertical adjustment of said units, and means 'or retaining the tongues in said recesses;

4. In a roof construction, a pair of covering units notched at their opposite side edges, forming a recess, a third covering unit overlying said pair of units and provided at its 2o lower end with a locking tongue lying flush in said recess,'the latter being Wider than said tongue, permitting lateral adjustment of the units and being also of suicient length to permit Vertical adjustment of saidl units, and

me-ans for retaining the tongue in said recess.

5. In a roofing construction, a pair of ilexible diagonally-laid shingles notched in their opposing side edges, forming a recess, athird shingle overlying said pair and pro-vided at im its lower end with a locking tongue lying in said recess, the latter being wider than said tongue, permitting lateral adjustment of the last-named shingle relative to said firstnanied pair, and means for retaining the tongue in said recess.

6. In a roofing construction, a pair of iiexible diamond-shaped diagonally-laid shingles provided in their opposing side corners with notches, together forming a downwardly- 40 opening recess, a third shingle overlying said pair and provided at its lower end with a locking tongue lying flush in said recess, and means for retaining the tongue in said recess.

7. In a roofing construction, a pair of flexible diamond-shaped diagonally-laid shingles v provided in their opposing side corners with registering notches, forming a downwardly` opening recess, L-shaped staples whose stems penetrate the side portions of said pair re- 53 spectively, while their heads extend over said notches, and a third shingle provided at its lower corner with a turned-under locking tongue lying flush in said recess' and engaging under the hea-ds of said staples.
